Abstract: Without an increase in the cost, a movable range is defined. A first joint mechanism includes a base part, and a rotary part that rotates relatively to the base part. The first joint mechanism includes a regulated part that rotates together with the rotary part, a regulating part that is disposed on the extension of the rotation locus of the regulated part, and that has a function of regulating rotation of the regulated part relative to the base part, within a first movable range, and a movable range defining member that is disposed on either the base part or the rotary part, and that defines, as a movable range of the regulated part, a second movable range that is narrower than the first movable range.
